Definitions

  • the present invention relates to a 5-amino-2-phenoxysulfonanilide compound having anti-inflammatory, antipyretic, analgesic and antirheumatic actions.
  • An object of the present invention is to provide drugs having excellent anti-inflammatory, antipyretic, analgesic and antirheumatic actions.
  • the present invention relates to a 5-amino-2-phenoxysulfonanilide compound represented by Formula (I): and to pharmaceutically acceptable salts thereof.
  • the salt refers to salts with alkali metals (e.g. sodium and potassium), alkaline earth metals (e.g. calcium and magnesium), ammonia and organic bases (e.g. ethanolamine, lysine and arginine).
  • alkali metals e.g. sodium and potassium
  • alkaline earth metals e.g. calcium and magnesium
  • ammonia and organic bases e.g. ethanolamine, lysine and arginine.
  • the compound of Formula (I) of the present invention can be prepared, for example, by the following preparation steps (a) to (f).
  • the hydrolysis in this reaction may be a conventional hydrolysis of an amide under the basic or acidic condition, for example, a hydrolysis using lithium hydroxide, sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium methoxide, sodium ethoxide or potassium t-butoxide for the basic condition, or a hydrolysis using hydrochloric acid, hydrobromic acid or sulfuric acid for the acidic condition.
  • Examples of the solvent to be used in the reaction are water, methanol, ethanol, propanol, t-butanol, tetrahydrofuran, dioxane, benzene, toluene, xylene, chlorobenzene, N,N-dimethylformamide, dimethyl sulfoxide, formic acid and acetic acid, but it is preferably that the solvent is appropriately chosen depending on the condition of the hydrolysis.
  • the compound of the present invention can be administered orally or parenterally in the conventional dosage forms such as, for example, tablets, dusts, granules, powders, capsules, solutions, emulsions, suspensions and injections, all of which can be prepared by conventional practices.
  • the dose used for humans as an anti-inflammatory, antipyretic, analgesic or antirheumatic agent is different depending on the age and body weight of the patient, symptoms of the disease, route of administration and frequency of administration, but it is usually from 5 to 600 mg per day.
  • the compound which is an active ingredient in the present invention has potent anti-inflammatory, antipyretic, analgesic and antirheumatic actions with fewer side effects such as gastrointestinal disorders, and therefore it is useful as anti-inflammatory, antipyretic, analgesic or antirheumatic agents.
  • test drugs the compound (a) of the present invention and the control drug (b)
  • test drugs each suspended in 5% aqueous gum arabic solution in an amount of 1 ml per 100 g of body weight.
  • 0.1 ml of 1% carrageenin was administered subcutaneously into the left hind foot pad.
  • the volume of the foot was determined, and the edema inhibition rate (%) was calculated for the anti-inflammatory effect.
  • Dose of the test drug was 0.3 mg/kg.
  • mice Seven Lewis strain rats (for each group) were administered subcutaneously 0.7% Mycobacterium tuberculosis suspended in liquid paraffin into the left hind foot pad to induce adjuvant arthritis. 15 ⁇ 18 Days after administration of adjuvant, rats with fully developed arthritis were administered orally with test drugs [the compound (a) of the present invention and the control compound (b)], each suspended in 5% aqueous gum arabic solution in an amount of 1 ml per 100 g of body weight once a day for 4 days.
  • test drugs the compound (a) of the present invention and the control compound (b)
  • the volume of the foot was determined, and the edema inhibition rate (%) was calculated for the therapeutical effect.
  • Dose of the test drug was 0.2 mg/kg.
  • test drugs the compound (a) of the present invention and the control compound (b)
  • test drugs each suspended in 5% aqueous gum arabic solution in an amount of 1 ml per 100 g of body weight.
  • the occurrence of squeaking response was monitored with time over 5 hours after the administration, and the inhibition rate (%) was calculated to examine the analgesic effect.
  • Dose of the test drug was 1.0 mg/kg.
  • the compound (a) of the present invention the compound of Example 1.
  • Control compound (b) N-(4-nitro-2-phenoxyphenyl)methanesulfonamide
  • Healthy human peripheral blood heparinized was layered over Lymphoprep (Daiichi Pharmaceutical Co.) under aseptic conditions to remove red blood cell, and the cell counts were adjusted to 2 ⁇ 10 6 cells/ml by froating the cells in RPMI-1640 medium containing 10% fatal bovine serum, penicillin 100U/ml, streptomycin 100U/ml, HEPES buffer 10mM and L-glutamin 2mM.
  • the concentrations of the test drug were 0, 3, 10 and 30 ⁇ g/ml.
  • IC 50 value of the 1L-1 formation inhibiting action of the compound (a) of the present invention was 13.3 ⁇ g/ml, but the control compound (b) did not show 50% or more inhibition in the above concentration, and therefore the IC 50 value could not be calculated.
